Originally developed by leading bilingual educators under the direction of Dr. Alba Ortiz (University of Texas - Austin) and revised by Dr. David Francis, Dr. Coleen Carlson, and Elsa Hagan of the Texas Institute for Measurement, Evaluation, and Statistics (TIMES, University of Houston), Tejas LEE® is a research-based K-3 assessment of reading and related skills for students receiving primary literacy instruction in Spanish.

mCLASS®:Tejas LEE® software, created by Wireless Generation in collaboration with TIMES and the Texas Education Agency (TEA), delivers the same trusted assessment on a handheld computer with tools for streamlined administration, reporting, diagnosis and data-driven instructional planning.
